The drill core was logged, sawed, and half cores were sampled in their entirety in two meter intervals at the Company's core processing facility located in Copiap?, Chile. Samples were shipped to Acme Analytical Laboratories sample preparation facility also in Copiap?, and pulps were forwarded to the Acme lab in Santiago, Chile. Samples were crushed, split and 500g was pulverized to 85% passing 200 mesh. Gold analyses were by fire assay fusion with AAS finish on a 30g sample. Copper was analyzed by AAS using a 4 acid digestion and samples were also analyzed for a suite of 36 elements with ICP-ES. Copper and gold standards as well as blanks and duplicates (field, preparation and analysis) were randomly inserted into the sampling sequence for Quality Control. On average, 9% of the submitted samples correspond to Quality Control samples.

At the GJ project in B.C., the Main and North Donnelly Zone resource estimate was prepared by qualified person Mr. Gary Giroux. P.Eng. using a computer-generated block model based on approximately 42,000 metres of diamond drilling in 169 drill holes. A total of 9,883 assayed samples were used to define the resource. The drill programs and sampling were supervised by qualified person David Mehner, P.Geo., Project Geologist for NGEx Resources (Canadian Gold Hunter). Appropriate quality control and quality assurance protocols were utilized on the program. Standard reference samples, blanks and duplicates were inserted in each batch of samples for assay. The drill samples were analyzed for gold by fire assay / atomic absorption and for copper by ICP and by atomic absorption for those samples over 1%, by ALS-Chemex in North Vancouver, B.C., Canada. All assay results were examined by independent engineer Dr. Giles Peatfield, P.Eng.
